Title: Pressure transducer assembly
Inventor: MCCORD KENNETH R
IPC: A61B5/00
Filed: 1984-04-12
Granted: 1988-03-03
Abstract: A pressure transducer assembly (10) is disclosed for directly monitoring pressure in a fluid which flows through the assembly. The assembly includes a housing (16) defining a chamber (18) therewithin and having an inlet port (26) and an outlet port (28) in fluid-flow communication with the chamber. An electrically insulated body element (24) is sealed within the chamber dividing the chamber into a first chamber (20) and a second chamber (22). The first chamber is in fluid-flow communication with the inlet and outlet ports. The second chamber is separated from the first chamber by a fluid-tight seal such that any fluid present in the first chamber cannot enter the second chamber. A pressure transducer sensor (32) is secured in the insulated body and exposed to the first chamber such that the sensor can determine the pressure in a fluid in the first chamber and convert the pressure into electric impulses. The sensor is separated from the fluid in the first chamber by an insulating medium (34) across which fluid pressure can be determined. Connected to the sensor are electrical conductors (36) which extend through the insulated body and into the second chamber. The second chamber provides an engagement site for an electrical connector (38) which can inte- connect with the electrical conductors and provide an electrical path through which the electric impulses generated by the sensor can be transferred to a monitor (56).

Granted: 1989-11-09
Abstract: An electromagnetic pump comprising a housing (12) having a fluid receiving chamber (14) in communication with an inlet (20), a pair of fluid chambers (16, 18) connected by a fluid bypass passage to accommodate bubbles, one chamber (16) in communication with the fluid receiving chamber (14) and the other chamber (18) in communication with an outlet (22), an electromagnet (80) carried by the housing (12) located external to the fluid chambers (14, 16, 18) thereof, and a barrier in the form of a thin diaphragm (90) of fluid impermeable material which hermetically isolates the electromagnet (80) from the fluid chambers (14, 16, 18). An armature (120) in the housing (12) is movable within a body (100) of magnetically permeable material which contains the bypass passage (110), has a pole portion (124) located for magnetic attraction by the electromagnet, and has a piston portion (150), preferably of smaller cross-section than the pole portion (124), for forcing fluid from the fluid chambers and through the outlet (22). The armature (120) is moved from a rest position through a forward pumping stroke when attracted by the electromagnet (80) and is moved by a biasing spring (160) in an opposite direction through a return stroke back to the rest position. A main check valve (170) is movably carried by the armature (120) and located in the fluid receiving chamber (14) for closing the pump inlet (20) when the armature (120) is in the rest position and allowing opening the inlet (20) after the armature (120) beings the forward pumping stroke. The structure and arrangement of the main check valve (170) minimises the volume of the fluid receiving chamber (14) to limit the maximum size of a bubble contained therein. A bypass passage (180) containing a check valve (186) which opens during the armature return stroke provides a path for bubbles around the piston (150) to the fluid receiving chamber (14).

Patent DE-3585768-D1 (DE)
Inventor: NEWHOUSE DANIEL L
IPC: G01N35/00
Filed: 1985-09-17
Granted: 1992-05-07
Abstract: In a microprocessor-controlled evaporation/concentration system, a plurality of sample solutions are automatically successively delivered to an evaporation chamber (11,27) for evaporation and/or concentration. Each sample solution is evaporated in successively delivered slug components whereby each slug is delivered for temporary storage into one of two storage loops (22, 23) while the previous slug is transferred from the other loop to the evaporation chamber. The evaporation chamber (27) has a ceramic bottom wall (29) with known thermal transfer properties. The underside of the bottom wall is maintained at a microprocessor-determined constant evaporation temperature by an electrical resistance heater (30) and proportional temperature controller (31). Pressure in the chamber is maintained substantially on the vapor pressure versus temperature curve of the sample solution, thereby assuring a known evaporation rate. Valving (V14) controlled by the microprocessor permits automatic addition of diluent to the chamber to form a prepared solution of known concentration with the residue from the evaporated sample. The prepared sample is then automatically transferred to one of multiple storage vials (41) which are brought into successive registration with a syringe needle assembly (44) by means of a rotatable vial storage tray (40). The microprocessor (15) automatically cleanses the entire flow system with cleansing solution and/or purging gas after each sample has been evaporated/concentrated.

Abstract: In a processing machine which operates with an arc, for example, a burning cutting installation, the arc current is measured and regulating signals are derived from the measurement value for the purposes of regulating the tool-workpiece spacing. In that procedure the analog measurement value is converted by a converter into high frequency signals whose frequency corresponds to the respective measurement value, the high frequency signals are fed to a regulator and therein are converted again into analog and/or digital signals. Also provided is a capacitive or inductive spacing measuring means which is also connected to the converter so that the arc current measurement values and the spacing values of the capacitive or inductive measuring arrangement are processed by the same converter means and evaluation circuit.
